Introduction
This document forms part of a series of European Standards, written by CEN/TC 350, that provide a
system for the sustainability assessment of buildings and civil engineering works using a life cycle
approach. The sustainability assessment quantifies aspects and impacts to assess the environmental,
social and economic performance of buildings and civil engineering works using quantifiable indicators
measured without value judgements. The purpose of the standards developed under this framework is
to enable comparability of the results of assessments. The European Standards developed under this
framework do not set actual benchmarks.
The sustainability assessment of buildings and civil engineering works uses different types of
information. The results of a sustainability assessment of a building and/or civil engineering works
provide information on the different types of indicators, the related works scenarios, and the life cycle
stages included in the assessment.
In carrying out assessments, scenarios and a functional equivalent are determined at the construction
works level. This means that the descriptive model of the works with the major technical and functional
requirements has been defined in the client’s brief or in regulations, as illustrated in Figure 1.
Assessments can be undertaken for the object under consideration that is a whole building or civil
engineering works, a part of the works or a combination of several buildings and/or civil engineering
works.
Although the evaluation of technical and functional performance is beyond the scope of the standards
developed under this framework, the technical and functional characteristics are considered by reference
to the functional equivalent of the object of assessment. The functional equivalent takes into account the
technical and functional requirements and forms the basis for comparisons of the results of the
assessment under the basic principle that the functional equivalent is being fulfilled, when those set
technical and functional requirements are being met or exceeded. Therefore, the concept of functional
equivalent is used in this context instead of the concept of functional unit.
Figure 1 shows schematically how the functional equivalent and the following required technical
characteristics and functionality of the construction works are to be fulfilled by provided technical
characteristics and functionality. These all are communicated as illustrated in the box “Communication
of:”, so that those technical characteristics and functionality provided by the construction works that
exceed from those required, either by the client’s brief or through regulations, are to be communicated
together with the results of the assessment. Furthermore, any particular demands for, or related to, the
environmental, social and economic performance defined in the client’s brief, or in regulations, are to be
communicated, if relevant.
NOTE The outer box with the red dotted line represents the area standardized by CEN/TC 350.
Figure 1 — Concept of sustainability assessment of construction works
In concept, the integrated performance of construction works incorporates environmental, social and
economic performance as well as the technical and functional performance, and these are intrinsically
related to each other. Although the assessment of technical and functional performance does not form
part of this series of standards, their interrelationship with environmental, social and economic
performance is a prerequisite for an assessment of sustainability of construction works and, therefore, is
taken into account, as illustrated in Figure 1.
The users’ activities associated with the constructed asset (referred to as “users’ activities”) are part of
the assessment of construction works. These can include, for example, the fuel consumed by the cars
using a road as part of the assessment of infrastructure, or the energy used for commuting to and from a
building, as part of a building assessment.
It is advisable to carry out an assessment at the earliest opportunity during the conceptual/initial
planning stages of a construction or refurbishment project. This will allow a broad estimate of the
environmental, social and/or economic performance to be determined. As the project evolves, the
assessment may be periodically reviewed and updated to support decision-making. A final assessment
(as-built) should be carried out. The results of this final assessment can be used to inform all parties
concerned, and also serve as the database for future new similar projects.
NOTE 1 The coloured boxes represent the current work programme of CEN/TC 350.
NOTE 2 Functional requirements are part of client’s brief and building regulations.
Figure 2 — Work programme of CEN/TC 350
As described in the Figure 2, this framework is the general framework for sustainability assessment of
buildings and civil engineering works. The purpose of this EN 15643 is to provide a framework with
principles, requirements and guidelines for the assessment of the environmental, social and economic
performance of a building and/or civil engineering works or combination thereof at the “framework
level”. This document has been drafted by combining the previously published 5 parts of the framework
standards; i.e. EN 15643-1, -2, -3, -4 and -5 into one framework standard.
The documents developed under this framework for the assessment of the construction works,
EN 15978, EN 16309, EN 16627 for buildings and EN 17472 for civil engineering works, contribute to
the achievement of United Nations Sustainable Development Goals (SDG). The SDG icons are shown
below in Figure 3.

1 Scope
This document provides principles and requirements for the assessment of environmental, social and
economic performance of buildings and civil engineering works taking into account their technical
characteristics and functionality.
NOTE 1 Assessments of environmental, social and economic performance are the three aspects of sustainability
assessment of buildings and civil engineering works, or combination thereof, (hereafter referred to as “construction
works”).
The framework applies to all types of construction works and it is relevant for new construction works
over their entire life cycle, and of existing construction works over their remaining service life and end of
life stage.
The sustainability assessment of construction works covers aspects and impacts of construction works
expressed with quantifiable indicators. It includes the assessment of the construction works’ influence
on the environmental, social and economic aspects and impacts on the local area (area of influence) and
of the local infrastructure beyond the curtilage of the building and the civil engineering works.
NOTE 2 The sustainability assessment in the standards developed under this framework encompasses potential
impacts e.g. intrinsic hazards from chemicals that are not based on a full environmental risk assessment.
The assessment of environmental, social and economic aspects of organizations, such as management
systems, are not included in the standards developed under this framework. However, the decisions or
actions that influence the environmental, social and economic performance of the object of assessment
can be taken into account where the assessment includes management process related aspects.
